"nForce2 Ultra 400 has been around since July 2003, some seven months. Plain nForce2 has been around for over a year. While KT880 may boast better base features than nForce2 in some respects (SATA), it's still deficient and reliant on other chips for others (FireWire).
With NVIDIA ruling the 32-bit AMD enthusiast market with iron fists, VIA are going to find it hard to break into the market with KT880, given that performance is barely more than KT600, if at all, and it still lags behind NVIDIA's effort in that respect."
